Core Routes

NetDefendOS automatically populates the active routing table with Core Routes. These routes are

present for the system to understand where to route traffic that is destined for the system itself.

There is one route added for each interface in the system. In other words, two interfaces named lan

and wan, and with IP addresses 192.168.0.10 and 193.55.66.77, respectively, will result in the

following routes:

Route # Interface Destination Gateway

1 core 192.168.0.10

2 core 193.55.66.77

When the system receives an IP packet whose destination address is one of the interface IPs, the

packet will be routed to the core interface. In other words, it is processed by NetDefendOS itself.

There is also a core route added for all multicast addresses:

Route # Interface Destination Gateway

1 core 224.0.0.0/4

To include the core routes when you display the active routing table, you have to specify an option

to the routing command.

Example 4.2. Displaying the Core Routes

This example illustrates how to display the core routes in the active routing table.
